Problem 1
What is a gene pool? How would you determine the allele frequencies in a gene pool?
5 step solution
Problem 2
Define equilibrium population. Outline the conditions that must be met for a population to stay in genetic equilibrium.
2 step solution
Problem 3
How does population size affect the likelihood of changes in allele frequencies by chance alone? Can significant changes in allele frequencies (that is, evolution) occur as a result of genetic drift?
4 step solution
Problem 4
What is the Hardy-Weinberg principle? How does it explain the process of genetic drift?
4 step solution
Problem 6
Explain the effects of mating within a population on the distribution of genotypes and phenotypes in that population.
4 step solution
Problem 7
What is sexual selection? How is sexual selection similar to and different from other forms of natural selection?
